create empty array in matlab

main.m
        ```matlab
        empty_array = [];
        ```
        
        This will create an empty array of size 0x0. You can also create an empty array of a specific size and data type using the `zeros` function:
        
        ```matlab
        empty_array = zeros(1, 0); % creates an empty row vector
        empty_array = zeros(0, 1); % creates an empty column vector
        ```
        
        In both cases, the resulting arrays have a size of 0x0.
